1990 1. A constant mass undergoes uniform acceleration when the resultant force acting on it A is proportional to the displacement from a fixed point. B is proportional to the velocity. C is zero. D is constant but not zero. E increases uniformly with respect to time. 2. Two blocks‚ X and Y‚ of masses m and 2m respectively‚ are accelerated along a smooth horizontal surface by a force F applied to the block X‚ as shown in the diagram. [pic] What

spectrometer are shown in the following diagram. The functioning of this instrument is relatively straightforward. A beam of light from a visible and/or UV light source (colored red) is separated into its component wavelengths by a prism or diffraction grating. Each monochromatic (single wavelength) beam in turn is split into two equal intensity beams by a half-mirrored device. One beam‚ the sample beam (colored magenta)‚ passes through a small transparent container (cuvette) containing a solution

Please complete this section of your write-up as you work on the experimental portion of this lab. 1. Hold the grating several inches from your face‚ at an angle. Look at the grating that you will be using. Describe what you see at the grating surface. I see different color of the rainbow and when I change the angle that am holding the diffraction grating Hold the grating up to your eye and look through it. Describe what you see. Be specific. When I look to the light source directly

Persian Gulf Pearl History Since the past‚ persian Gulf was one of the greatest source for fine and perfect pearls. Persian Gulf oysters (Pinctada margaritifera‚ Pinctada radiata) were collected for their mother-of-pearl‚ which was used as an inlay material in ancient Egypt as early as the sixth dynasty (c 3200 BC). The pearls of the Persian Gulf were natural created and collected by breath-hold divers. The secret to the special luster of Gulf pearls probably derived from the unique mixture of
